theme fixer many issues

I am having many issues to install and set up the fixer theme, I would like to have it installed with this app and with your plugins, I can't see my changes on Windows computer for example and many other issues when I edit the them, I choose this app for all the plugins and for this theme but its giving to me many issues.
Is there a guide for this theme? An installation guide? Someone for support?

Also, I see a console error on your site which may be causing some issues with Fixer, especially background images, can you try adding below code in your wp-config.php file just above /* That's all, stop editing! Happy blogging. */ line and see if that makes any difference:define('UPFRONT_DEBUG_LEVELS', 'dependencies');

If you're still having issues after applying the above code can you give us some more info about the issues you're experiencing?

Also, can you tell us which browser are you using and have you tried using different one to see if issue could be related to that?
